论中国古代治边思想的特点、演变和影响

古代治边思想大体形成于秦汉,发展和延续至清代,其内涵是动态变化的,经历了从肤浅到成熟的过程,各个时期的治边思想又有其特色。古代治达思想总体上有两个基本的特点：统治对开疆拓土多持相对保守的态度,认为理想的边疆治理是“守在四夷”;从“华夷有别”的治边观出发,在边疆地区施行相对宽松的羁縻统治,同时重视在边疆传播封建化的教化作用。章还以封建统治对边疆民族的治策和对边疆的经济开发为例,阐述了古代治达思想对边疆治策的广泛影响。     

Exposure to Cadmium and Lead in an Agropastoral Iron Age Population

Metals present in the environment (soil, water and atmosphere) can affect food safety and human health through bio‐accumulation and bio‐magnification phenomena. Human exposure to the metals may take place through the environment and by ingesting contaminated food (including water), determining harmful effects usually detectable over the long term. Starting with the Industrial Revolution, local occurrence and concentration of metallic contaminants in the environment have been exponentially increasing: it has been assessed that, nowadays, daily absorption of lead, by North American people, is noticeably greater than that during prehistoric times. In this study, we measured concentrations of cadmium, lead and zinc in 153 bone samples (femurs) of Iron Age inhabitants of Central Italy (Abruzzo): the Samnites from the Alfedena Necropolis (2600–2400 bp ). The data found are in agreement with the results of similar published studies. Heavy metal concentrations varied widely among samples with the exception of zinc. A significant difference (p same Mann–Whitney test <0.05) in cadmium bone levels was found between male (0.08–1.8 mg/kg, median 0.31 mg/kg) and female samples (0.05–1.3 mg/kg, median 0.53 mg/kg).

Pre-Hispanic gold pieces of an enigmatic archaeological finding in Medellín,Colombia: A glance at an archaeometric analysis

The study analysed pre-Hispanic gold objects found within a surprising archaeological finding of a structure that likely served as a funeral pyre in Medellín, Colombia. ¹⁴C analyses of the site's organic materials dated the structure to the fifth century ce . The metal objects were subjected to X-ray diffraction (XRD), energy-dispersive X-ray fluorescence (EDXRF), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), density measurement by the Archimedes method, and metallographic analysis. The measurements by EDXRF and SEM-EDX showed that the pieces were composed mostly gold and silver. The XRD results indicated that the microstructure of the objects corresponded to a single phase of gold and silver. The images obtained by the metallographic microscope showed equiaxial grains with some twins, a structure consistent with annealed metals. The different colours observed correspond to different grain orientations. Pre-Hispanic objects from a second archaeological site in the municipality of Amalfi (Department of Antioquia) were also analysed for comparative purposes. The results showed that the gold objects were not subjected to any alloying process, but were instead manipulated in their original form (native gold). The shape of the objects and their microstructural results suggested that the pieces were manufactured by casting, mechanical deformation and then annealing.     

MIGRATION AND NARRATION: HOW EUROPEAN HISTORIANS IN THE NINETEENTH AND EARLY TWENTIETH CENTURIES TOLD THE HISTORY OF HUMAN MASS MIGRATIONS OR VÖLKERWANDERUNGEN

Historians’ interest in the history of human migrations is not limited to recent years. Migrations had already figured as explanatory factors in connection with cultural and historical change in the work of classical and ancient studies scholars of the late nineteenth and early twentieth centuries. In the writings of these scholars, migrations acted as historical landmarks or epochal thresholds and played a key role in the construction of geo-historical areas. This model has been called “migrationism” and cannot be explained simply on the basis of the history of individual disciplines, but must be seen in its complex interaction with scientific and historical contexts. However, “migrationism” does not relate to fixed political and scientific positions or movements. For this reason, it cannot be explained adequately by using a historically or ideologically based approach. Relying on narratological approaches, this article examines migration narratives that historians of this period used to explain the rise and fall of ancient civilizations. Referring to contemporary historiographical representations of the ancient Near East, it distinguishes three main narratives that are still common today: narratives of foundation, narratives of destruction, and narratives of mixtures. In this sense, analyzing older migration narratives helps us to sharpen the critical view on the genealogy of our own views on the history—and present—of human migrations.     

茂县及岷江上游地区在古蜀文明形成中的重要作用与地位

"古蜀文明"即"三星堆文明",形成的时间大致在公元前1600年~前1500年之间。三星堆文明形成时期的代表性文明因素主要有3种:一是以三星堆城址城墙为代表的本土文明因素,二是以具有二里头文化特征的文化遗存为代表的中原文明因素,三是以具有齐家文化特征的文化遗存为代表的甘青地区文明因素。后二者是通过早在公元前3500年前后就已经形成的岷江上游地区的文化通道,由陇西南进入成都平原地区,并促使成都平原本土文化发生巨变,产生了三星堆文明,开始了古蜀文明的历程。三星堆文明的形成过程反映了岷江上游地区在古蜀文明的形成这一重大历史事件中,发挥了无可替代的桥梁作用。     

基于磁化率测量平遥古城古砖的烧制温度

古砖的烧制温度决定了其物理力学性质。本研究提出基于磁化率来确定古砖烧制温度的方法。通过对古砖重新加温,测量不同温度下古砖的磁化率,得到磁化率差值的平方-温度曲线图。图中第一个较大的偏差对应的横坐标即为古砖的烧制温度。利用上述方法测得实际烧制温度为700℃、800℃和900℃的黏土砖的烧制温度分别为690℃、810℃和870℃。二者误差较小,认为利用该方法确定砖的烧制温度可行。本研究利用该方法确定了平遥古城10块古砖的烧制温度,发现其烧制温度在650～690℃和850～870℃两个区间范围内。据此推测平遥古城古砖是以秸秆和木柴为燃料烧制而成。本研究实验结果可为古建筑修复和保护提供理论参考。     

唐代黑水都督府的历史地理学考察

唐开元年间先后在渤海北境、黑水靺鞨地方设置勃利州、黑水军、黑水都督府。从文献与考古材料双重视角入手,可以对与黑水都督府建置有关的勃利州(渤州)、黑水靺鞨道、渤海都督府、安静都督府、黑水靺鞨思慕部等问题进行梳理和考索,又结合渤海与黑水靺鞨军事对抗导致黑水靺鞨自牡丹江中下游不断北移的历史背景,再考黑水都督府的具体地望。研究渤海都督府、安静都督府辖区以及黑水靺鞨思慕部相对位置关系,又考虑其为具有地区战略意义的和扼守渤海上京以北、贯穿南北黑水靺鞨交通孔道的军政重镇,萝北县江岸古城当为唐开元年间设置的黑水都督府治所所在。     

A Model for Assessing the Reuse of an Ancient Place of Performance: The Bouleuterion of Teos

Ancient places of performance are often considered for reuse as a means of promoting archaeological sites. Therefore, local authorities and decision makers have a difficult task of balancing the conservation and management of the sites with the carrying capacity. In this paper, the bouleuterion, a ‘rediscovered’ structure, at the Teos archaeological site, in Turkey is evaluated and presented as a preliminary case study with the hopes that these issues will be taken into consideration by the managing body in the creation of a management plan for the site. The evaluation is made by assessing socio-economic and intangible heritage significance, policies guiding changes at the site, a qualitative survey at the site and by defining the structure’s carrying capacity. The site’s strengths, weaknesses, opportunities, and threats are used to create criteria and make proposals for its reuse. The study concludes that the bouleuterion cannot be reused as a venue in its present condition and makes recommendations for future use.     

基于海量点云数据的大雁塔三维重建

古建筑三维重建已成为历史遗迹保护与修复的重要内容。为了探讨三维激光扫描数据的获取流程、数据处理方法,以三维激光扫描获取的大雁塔海量点云数据为例,研究了古建筑三维重建中点云数据获取与处理的详细过程。联合Cyclone、AutoCAD和3D-Max软件的优点构建了大雁塔真实的横面、剖面、立面模型,其中重点研究了海量点云数据在Cyclone软件中分块建模的方法。结果表明:将拼接好的大雁塔海量点云数据分块建模,不仅加快了数据处理的速度,而且符合精度要求。在点云数据拼接时采用标靶拼接和同名点拼接相结合及测站间两两拼接之后再整体拟合平差的方法,减少了拼接中的误差,使每站拼接误差都不超过3cm。在建模过程中的墙体拟合是上万个点云经过平差计算得到,精度高达2mm。最后在3D-Max软件中组合、渲染和贴图,真实地构建了大雁塔三维立体模型。为古建筑数字化存档和后期的修缮工作提供了重要的依据。
